So another detail to ponder is that canonically, John the Baptist never drank wine, and traditionally, neither did James the Just.

Yet the ritual for taking part in salvation necessitated drinking wine (especially as the doctrine of transubstantiation developed later on)?

So his mentor and brother couldn’t partake?

We see as early as Ignatius discussion of a different Eucharist tradition, where he chastises the schismatic use of “evil herbage.”

It’s not a very straightforward development.
